Description

Technical Field

[0001] The utility model relates to the technical field of automobile air conditioners, in particular to an air conditioner anti-cross-wind air inlet structure. Background Art

[0002] Automobile air conditioners are ventilation devices that are used to adjust and control the temperature, humidity, air cleanliness and air flow in the car compartment to the optimal state, provide passengers with a comfortable riding environment, reduce travel fatigue, create good working conditions for the driver, and play an important role in ensuring safe driving. They generally include refrigeration devices, heating devices and ventilation devices.

[0003] The ventilation device mainly refers to the internal circulation and external circulation of the car air conditioner. The internal circulation means that the blower sucks in the air in the car and blows it into the car without the participation of the air outside the car. The advantage is low energy consumption and fast cooling and heating. The disadvantage is that it is not conducive to the renewal of the air in the car. The external circulation means that the blower sucks in the air outside the car and blows it into the car. The advantage is that the air in the car can be continuously renewed. The disadvantage is high energy consumption and slow cooling and heating.

[0004] The existing air conditioning anti-cross-wind intake structure is generally improved to address the defects of the above-mentioned ventilation and air exchange devices. For example, the authorized Chinese patent CN219523623U discloses an automobile air conditioning anti-cross-wind intake structure, which can be achieved through a main body, a left shell, a right shell, a filter element, an external circulation damper, an arc plate, a fan-shaped plate, a straight plate, an anti-cross-wind damper, a rotating shaft, a first baffle, a second baffle, an air outlet, a first sealing strip, a second sealing strip, a first boss, a second boss, a compensation shaft, a first limit plate, a second limit plate, a third limit plate, The third baffle, the fourth baffle, the first motor, the second motor, the crank assembly, the compensating air outlet, the internal circulation air outlet, the fresh air outlet, the fresh air channel, the internal circulation channel, the compensating air duct, the first partition plate and the third sealing strip and other structures are used in combination to separate the fresh air channel and the internal circulation channel on both sides of the first baffle, avoid contact between the airflow in the internal circulation channel and the airflow in the external circulation channel, reduce the probability of cross-flow, and avoid high-velocity airflow outside the car from entering the car in the opposite direction along the internal circulation channel, thereby ensuring that the air entering the car can pass through the filter element.

[0005] However, when installing the filter element of the automobile air-conditioning anti-cross-wind intake structure in the above-cited document, the filtering end of the filter element needs to face outwards in order to filter the air it transports. The traditional filter element does not have an anti-stuck structure, so that both the positive and negative ends of the filter element can be inserted and installed normally, which makes the filter element easy to be reversed, and thus cannot perform the filtering operation normally; secondly, the filter element itself is relatively soft in texture, and the traditional installation method is to directly insert the filter element for installation, which is easy to damage the filter element during installation, thereby reducing the filtering effect, and does not have a combined installation structure when inserted, so that the filter element installation effect of the existing air-conditioning anti-cross-wind intake structure needs to be improved.
